I just bought a Nuova Simonelli Musica + Eureka Mignon, so I'm practicing extracting a shot.
I am trying to make the extraction lasts 25 sec.
But when I start the extraction, I first have preinfusion time that last like 3-5 sec, and then the pump starting, that is lasting like 3 sec also.
So, at what time should I begin to count 25 sec ??? At the beginning ? After the preinfusion time ? Or when I see expresso out of the machine ?
